limiting antibiotic resistance

  • hospital acquired infections(HAI)
    increased by poor hygeine practices eg
    • not washing hands regularly
    • uncontained coughing/sneezing
    • failing to disinfect equipment/surfaces after use
  • how to reduce HAI
    • wash hands regularly
    • isolation wards if patient has HAI, they are screened at arrival, isolated and treated
    • surfaces/equipment disinfected after every use
  • antibiotic resistance
    • resistance is a result of natural selection
    • bacteria not killed posses a selective advantage(resistance) thus can survive and reproduce
    • allele for antibiotic resistance passed onto offspring= resistant strain
  • reducing resistance
    • no antibiotic prescription for minor infections/viral diseases
    • no use of antibiotics as a preventative measure
    • rotate use of different antibiotics-reduce chance of bacteria developing resistance
  • reducing resistance
    • prescription of narrow spectrum antibiotics:
    -active against a narroe range of bacterial infections
    -any resistance genes that arise will not cause a problem if transferred to other bacterias as those are treated with different antibiotics(exchange genes via horizonal gene transfer)
